We're dividing 248064 by 20 
We're looking to find how many times 20 goes into 248064.

Let's proceed to step 1:
2 divided by 20 is 0 with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Grab the next digit (4) from the dividend, add it to 2, then carry on: 24 / 20

Going ahead to step 2:
24 divided by 20 is 1 with a remainder of 4.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 20 away from 24, we end up with 4.
Bring next digit (8) of the dividend behind the 4 and repeat the process: 48 / 20

On to step 3:
When dividing 48 by 20, we get 2 with a remainder of 8.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
Deduct 40 from 48 and we're left with 8.
Include the next digit (0) from the dividend after 8, then repeat: 80 / 20

Step 4:
20 can be fit into 80 4 times, resulting in a remainder of 0.
Write down 4 as next digit of the result. 
Result so far: 124.0
The remainder is 0 after subtracting 80 from 80.
Append the next digit (6) from the dividend to 0 and continue with: 6 / 20

Moving on to step 5:
If we divide 6 by 20, we get 0 and a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 1240.0
The remainder is 6 after subtracting 0 from 6.
Fetch the next digit (4) from the dividend, attach it to 6 and continue: 64 / 20

Let's proceed to step 6:
The number 20 fits into 64 3 times, leaving a remainder of 4.
Record the quotient 3 as the next digit in the result. 
Result so far: 12403.0
If we subtract 60 from 64, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 7:
40 divided by 20 is 2 with a remainder of 0.
Write down 2 as next digit of the result. 
Result so far: 12403.2
Deduct 40 from 40 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 8:
20 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 12403.2
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 9:
If we divide 0 by 20, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 12403.2
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final result is 12403.2 with a remainder of 0.0.
